Cardiac prosthetic devices are used to replace damaged or diseased natural valves of the heart. These devices increase the survival rate and improve the quality of life in most patients. The cardiac prosthetic devices encompass heart valves as well as pacemakers. An artificial heart valve is a device implanted in the heart of a patient with valvular heart disease. There are three main types of artificial heart valves: the mechanical, the biological, and the tissue engineered valves. Cardiac pacemaker devices are small, battery-operated devices that senses heart beating irregularities and sends a signal to heart to makes it beat at the adequate pace. A variety of heart valves and pacemaker available in the market are mechanical heart valves, tissue heart valves, transcatheter heart valves, implantable pacemaker and external pacemaker.
